Swedish regulations on usage of two-component epoxy in relining
Relining is a method used for renovating tap water pipes in a building or in the ground by covering the interior of the existing pipes with a thin layer of plastic. This layer of plastic might be an epoxy-based material or another material.
Ban on two-component epoxy which contains bisphenol A or bisphenol A diglycidylether
In Sweden, there is a ban on certain epoxy-based materials when renovating tap water pipes by means of use a relining. According to the ban, two-component epoxy which contains bisphenol A or bisphenol A diglycidylether must not be used when casting new plastic pipes within old tap water pipes. The ban only applies to chemical products that consist of a base and a hardener which are mixed at the place of the casting.
Prevent bisphenol A in tap water
Epoxy-based materials which are used when renovating tap water pipes may contain and emit bisphenol A (BPA). In this context, tap water pipes refer to pipes intended for drinking water and hot water for consumption.
Bisphenol A is a substance with endocrine disrupting properties, and also classified as toxic for reproduction. At present the recommended concentration of bisphenol A that may cause negative effects for human health is debated and it is believed that effects may occur at even much lower concentrations. To prevent that bisphenol A is emitted into tap water, a Swedish ban on usage of certain epoxy-based materials in new renovations of tap water pipes by means of use a relining, applies from the 1 September 2016.
Exemption from the ban
If there are special reasons, the Swedish Chemicals Agency may grant an exemption from the ban. The application fee is 15.000 SEK. You must submit a written application and provide sufficient reasons for an exemption. We may only grant exemptions for individual cases.
